Speakers: Genetically Engineered Crops and their
Impact on Society
Dr. Wolfenbarger reported on
her recent participation in a National Academy of Science 18-month study on
genetically engineered farm crops focused on sustainability and impact on
society. Sustainability was
examined in terms of environment, economics, and societal impact. Because of controversies around
engineered crops, obtaining consensus was a challenge. The study report received peer review
and responded to over 500 comments on the outcomes.
The three main crops studied
were corn, soybeans, and cotton.
Approximately 80% of corn and cotton, and 90% of soybeans are currently
genetically engineered. The study
group looked at the effects on non-adopters, on soil and water, and on
biodiversity. In general, there
were fewer adverse effects on the environment and less use of herbicides. However, there is some concern about
decreasing resistance to glycocide herbicide.
Engineering also produces
crops that produce their own pesticides. All in all, engineering reduces costs through reductions in
herbicides and pesticides, but has not greatly changed yields, although it has
tended to reduce yield variability.
